<sys/types.h>: Reduce vm_* types pollution in userland.
Userland should not be using these types outside kernel structures or
<vm/*.h> scope. Adjust several userland and boot code sources to
include <machine/types.h> where they use them (mainly for vm_offset_t).
* sys/fbio.h: Used in several world utilities and libvgl.
* sys/kinfo.h: Use size_t for kp_vm_map_size (header used in userland).
* sys/emulation/ndis/pe_var.h: Used in ndiscvt(8).
* bus/firewire/fwcrom.c: Compiled directly in fwcontrol(8).
* mptable(1): include <machine/types.h>, should really not be using
vm_offset_t and looks to be suspiciously broken.
* sys/boot: For now include <machine/types.h> for vm_offset_t in
several headers, should really not be using vm types.
Rest of world utilities get vm types through <sys/user.h>.
While there, move pthread type inclusion to the very end of the source,
doing so improves readability of compiler intermediates a lot.
Strictly visibility changes only.
